Abstract. In 2012, two articles were published describing new species of the genus Chelotrupes Jekel, 1866 (Cole- optera: Geotrupidae); the fi rst one included fi ve new species and the second a single species. However, the species described in the second article, Chelotrupes annamariae Byk 2012, is identical to Chelotrupes algarvicus Hillert, Král and Schneider 2012 and should be considered a junior synonym: Chelotrupes algarvicus Hillert, Král and Schneider 2012 = Chelotrupes annamariae Byk 2012, syn. nov.

Introduction

Jekel (1866) fi rst established Chelotrupes as a subgenus of the genus Geotrupes Latreille, 1796 with Scarabaeus momus Olivier, 1789 as the type species. Subsequently, Boucomont (1912) considered Chelotrupes to be a subgenus of Typhaeus Leach, 1815 comprised of two species Typhaeus (Chelotrupes) hiostius (Gené, 1836) from Sardinia and T. (Chelotrupes) momus (Olivier, 1789) from the Iberian Pen- insula. Recently, Dellacasa and Dellacasa (2008) elevated Chelotrupes to genus rank and considered C. matutinalis (Baudi di Selve, 1870), formerly a synonym of C. hiostius (Gené, 1836), to be a valid spe- cies. In 2012, Hillert et al. published a detailed study of the genus Chelotrupes in the Iberian Peninsula in which they described fi ve new species, two from Spain (C. hendrichi and C. kyliesi) and three from Portugal (C. algarvicus, C. brancoi and C. feryi) and re-established C. laevipennis (Mulsant and God- art, 1855) as a valid species. The same year, Byk (2012) published the description of a new species, C. annamariae, from within the known distribution of C. algarvicus. The latter article only considers two species from the Iberian Peninsula, C. momus and the newly described species, and does not refer to the publication by Hillert et al. (2012). From its description, C. annamariae Byk 2012 appeared to be a re-description of C. algarvicus Hillert, Král and Schneider 2012, and this hypothesis is tested below.

Material and Methods

Specimens Studied. Specimens were fi rst chosen based on their geographical location (holotype, para- type or reported location of individual species in Hillert et al. 2012), and their identity checked based on external characters reported in the same publication. The aedeagus of the following male specimens were studied (all in collection of M. E. Miquel):

C. algarvicus: 6 sp., Portugal, Algarve, Sagres, 20.i.2013, leg. O. Boilly, 4 sp., Portugal, Faro, Vila do Bispo env., 10.xii.2012, leg. Ferreira P. C. brancoi: 1 sp.: Portugal, Estremadura, Setubal, N. of Alfarim, Sesimbra env., S. of Lisboa, 06.iii.2010, leg. O. Hil- lert, [paratype]. C. feryi: 1 sp., Portugal, Algarve, Armaç ã o de Pê ra, 26.x.2013, leg. Boilly O. C. hendrichi: 2 sp., Spain, Andalusia, Castillo de Castellar, Algeciras, env. 10km N. of San Roque, 02.iii.2008, leg O. Hillert, [paratype], 18-27.iii.2013, leg O. Hillert 2 sp.: Spain, Cadiz, Castillo de Castellar, 28-x-2013, leg. Boilly O. C. kyliesi : 1sp, Spain, Andalusia, Huelva, Aljaraque, 3715.425N 0704.078E, 25.ii.2009, leg.

(2012) was originally received on the 6th of Decem- ber 2011, accepted on the 27th of February 2012 and published on the 15th of August 2012; whereas the article by Byk (2012) was received on the 21st of October 2012 and accepted on the 15th of December 2012. Although, listed as published in November, all but one article in this issue of the Baltic Journal of Coleopterology were accepted on the 15th of December 2012 and consequently, the issue must have been published at the earliest on that date and not in November. In any case, the article by Byk (2012) has been both submitted and published after the publication date of the article by Hillert et al. (2012).

Geographical Origins of Type Materials. Holotypes of both species were described from the same locality: Portugal, Lagos, Vila do Bispo. For C. annamariae, a further thirty-fi ve paratypes were also studied, including twenty-fi ve from the type locality (twenty from the same series as the holotype), ten from Sagres (Lagos) and a museum specimen without precise locality (“Lusit.”). The municipality of Sagres is adjacent to the municipality of Vila do Bispo. For C. algarvicus, a further two hundred seventy-six (276) paratypes were studied from localities in the regions of Beja (Valle de Ferro) and Faro (including Carrapateira, Foia, Sierra de Monchique, Sagres and Vila do Bispo). In total, thirty-three paratypes came from Vila do Bispo and one hundred fi fty-one (151) from Sagres. Importantly, the same series of specimens from the type locality (Portugal, Lagos, Vila do Bispo, 7.xii.2006, leg. T. Gazurek) was used in both descriptions: holotype and twenty paratypes of C. anna- mariae and fi ve paratypes of C. algarvicus, discrediting the validity of the former.

Holotype Descriptions and Differential Characters. Descriptions given by Hillert et al. (2012) and Byk (2012), for both male and female, accurately match each other and, correspondence for each character can easily be established either in the text or the fi gures. To illustrate this point, mirrored descriptions for C. algarvicus are given for the characters used by Byk (2012) to differentiate C. annamariae and C. momus (Table 1). Photographs of the respective habitus are given in Fig. 4–7 for illustration. It fi rst appears that the aedeagus drawings of C. annamariae and C. algarvicus (Fig. 8–9) have marked differences that cannot be explained solely by the different drawing styles. However, on closer inspection it seems that the drawings for C. momus and C. annamariae have been inverted and taking this into account, the aedeagus do in fact match.

Aedeagus of Chelotrupes. In order to ascertain the above error, and to check for any variability in the shape of the aedeagus of C. algarvicus, ten specimens of the two localities of the type material of C. annamariae (Vila do Bispo and Sagres) were studied along with sixteen specimens of the other Iberian Chelotrupes. No variability was found within the specimens of C. algarvicus, and shape of the aedeagus of all species correlated well with diagrams provided by Hillert et al. (2012). This confi rms the observation by Hillert et al. (2012) according to whom the differences in the aedeagus of the seven species of Iberian Chelotrupes are small with C. algarvicus (Fig. 9) being well differentiated from the six other species (Fig. 11–16). Furthermore, the authors do not mention any variability within species. NEW SYNONYMY IN THE GENUS CHELOTRUPES INSECTA MUNDI 0344 January 2014 • 3

Aedeagi of at least six specimens of each species have been studied by Hillert et al. (2012) and those authors consider it to be the only strong differential character for minor males.

Conclusion

As it was described from the same locality and mainly from a series of specimens in part included in the description of C. algarvicus, and descriptions are in all manners identical, there is no possible doubt that C. annamariae is a re-description of the former species, albeit from a smaller and geographi- cally more restricted type series. According to the principle of priority (ICZN 1999), C. annamariae is a junior synonym of C. algarvicus.

Acknowledgments

I am grateful to Oliver Hillert for reviewing both an early and the fi nal version of the manuscript and for his pertinent comments on the aedeagi of the different species. I would also like to thank Olivier Boilly for reviewing the fi nal manuscript. 4 • INSECTA MUNDI 0344, January 2014 MIQUEL
